Description

technical field [0001] The invention relates to an airgel and a preparation method thereof, in particular to a graphene / conductive polymer aerogel and a preparation method thereof. Background technique [0002] Graphene is a two-dimensional crystal that is exfoliated from stone grinding materials and composed of carbon atoms with only one atomic thickness. In 2004, physicists Andre Geim and Konstantin Novoselov of the University of Manchester successfully separated graphene from graphite, confirming that it can exist alone, and they jointly won the 2010 Nobel Prize. Physics Prize. Graphene has a high electron mobility (2×105cm2(V S)-1), which is 100 times higher than that of silicon semiconductors and 20 times higher than that of gallium arsenide, while the resistivity is only about 10 -6Ω·cm. Therefore, it is expected to be used to develop a new generation of electronic components or conductive and heat-conducting films that are thinner and conduct electricity faster. ...
